Linux / Unix Command: md5sum
Command Library

NAME

md5sum - compute and check MD5 message digest  

SYNOPSIS

md5sum [OPTION] [FILE]...
md5sum [OPTION] --check [FILE]  

DESCRIPTION

Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard input.

-b, --binary
read files in binary mode (default on DOS/Windows)
-c, --check
check MD5 sums against given list
-t, --text
read files in text mode (default)
 

The following two options are useful only when verifying checksums:

--status
don't output anything, status code shows success
-w, --warn
warn about improperly formated checksum lines
--help
display this help and exit
--version
output version information and exit

The sums are computed as described in RFC 1321. When checking, the input should be a former output of this program. The default mode is to print a line with checksum, a character indicating type (`*' for binary, ` ' for text), and name for each FILE.  

SEE ALSO

The full documentation for md5sum is maintained as a Texinfo manual. If the info and md5sum programs are properly installed at your site, the command
